The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP-150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex 272.Chemorex CP-150 demonstrated an effective and selective extr...

The effect of heat treatment on the antioxidant activity of extracts from Citrus unshiu peels was evaluated. Citrus peels (CP) (5 g) were placed in Pyrex Petri dishes (8.0 cm diameter) and heat-treated at 50, 100, or 150 degrees C for 10, 20, 30, 40, 50, and 60 min in an electric muffle furnace. After heat treatment, 70% ethanol extract (EE) and water extract (WE) (0.1 g/10 mL) of CP were prepa...

Tumor suppressor p53 plays a major role in colorectal cancer development. The present study explores the effects of p53-modulating agent CP-31398 alone and combined with celecoxib on azoxymethane-induced aberrant crypt foci (ACF) and colon adenocarcinomas in F344 rats. Maximum tolerated doses were 400 and 3,000 ppm for CP-31398 and celecoxib, respectively. ACF and tumor efficacy endpoints were ...

BACKGROUND The use of cyclophosphamide in cancer therapy is usually associated with challenging immunosuppression which exposes patients to increased risk of anemia and necessitating preventive measures during therapy. This study was carried out to investigate the efficacy of the hydro-ethanolic extract of the root of Z. zanthoxyloides in preventing and/or improving cyclophosphamide induced mye...

A 2 × 2 factorial experiment was conducted to investigate the interaction between high and low dietary crude protein (CP) (200 v. 150 g/kg) and sugar-beet pulp (SBP) (200 v. 0 g/kg) on nutrient digestibility, nitrogen (N) excretion, intestinal fermentation and manure ammonia and odour emissions from 24 boars (n = 6, 74.0 kg live weight). The diets were formulated to contain similar concentratio...

Solvent extraction of copper from the copper leach solution obtained from the ammoniacal carbonate leaching of the Sarcheshmeh copper concentrate was carried out, and the performance of CP-150, LIX984N, and Kelex100 as well as the effects of different parameters involved were investigated. According to the results obtained, the extraction kinetics of all the three extractants was fast. High con...

Deli-style turkey breast cured with pre-converted celery juice powder (CP) or sodium nitrite (SN) was manufactured with ingoing SN concentrations or equivalent of 0, 50, 100, 150, and 200 ppm. Cured and total meat pigment, salt, and water activity were measured on d 0; color, pH, and residual nitrite were measured on d 0, 7, 14, 21, 28, 35, and 42. Untrained panelists evaluated sensory traits o...

Hepatoprotective potential of peroxisome proliferator activator receptor (PPAR)- α and - γ agonists, fenofibrate (FEN), and pioglitazone (PIO), respectively, against cyclophosphamide (CP)-induced toxicity has been investigated in rat. FEN and PIO (150 and 10 mg/kg/day, resp.) were given orally for 4 weeks. In separate groups, CP (150 mg/kg, i.p.) was injected as a single dose 5 days before the ...

Cisplatin (Cp) is one of the most effective chemotherapy antineoplastic drugs. Nevertheless, it causes numerous injurious effects on organs, precisely testes. Ixora coccinea (IC) a well-known medicinal herb and has long history use as tonic to promote health. This study revealed inhibitory hydroethanolic extract IC leaves (HEICL) CP-induced testicular damage in male Wistar rats. Thirty (30) adu...

The comparative in-vitro activity of CP-99219, a new quinolone, against Haemophilus influenzae (150 isolates), Moraxella catarrhalis (100), Streptococcus pneumoniae (80) and Group A beta-haemolytic streptococci (40) was determined using an agar dilution technique. CP-99219 was the most active compound tested against M. catarrhalis (MIC50 = 0.015 mg/L, MIC90 = 0.03 mg/L). Ceftriaxone, CP-99219 a...
